[Intra-masseter metastasis of a gastric adenocarcinoma].
We report a case of metastasis in the masseter muscle secondary to stomach carcinoma. Second neoplastic invasion in skeletal muscle is an exceptional phenomenon. And this frequency is paradoxical against corporeal muscular mass. Immune hypothesis is conjure up for explain this fact. Symptoms are not specific and the diagnosis is not often recognized. However, systematic postmortem investigation is positive in one per cent of the cases. Consequently, every painful and nodular induration involved in carcinoma supervision must do perform a systematic biopsy.
